Here’s a great how-to on building a “liquid fueled” rocket using little more than a fat Sharpie marker, a can of compressed air, and a few more supplies found down on the Cube Farm. The resulting rocket can fly up to 75 feet!

But hey there, John Glenn of the IT Department, BE CAREFUL! This is actually a project you don’t want to take lightly. Launch it outdoors, wear safety goggles, don’t “burn” yourself on the compressed air (it’s *very* cold). Generally, be smart, and use common sense whenever dealing with any type of projectile and components under pressure.

The innards are removed from the Sharpie and a port for the canned air tube is fashioned from a ball point pen tube and secured to the thrust end of the rocket.

The fins are made from electrical tape.

Plug the compressed air into the port on the business end the rocket, fill will gas from the can, and… BLAST OFF!

TIP: On the Comments to this Instructable, a maker suggests cutting off the bell-shaped end of another Sharpie and adding it to the thrust end of your rocket to form a De Laval nozzle for better thrust performance.
